Fanless Minarelli V1 Polini Kit Set Up.

I am trying to figure out an optimal system for running a Polini kit without a fan and with an air-cooled head (with doing a WC head as a backup idea). Is anyone running a reliable air-cooled, fanless Polini set up? Has anyone tried cross-cutting the fins on a Polini kit in an attempt to get better cooling? Thanks!

You can just run it without a fan. The fan on a V1 doesn't do a whole lot.

Angel loves to run without a fan

I love to run with a fan (it totally does quite a bit)

A good compromise is to use a metra 80 or Eurokit 80 head on it

.

Drops the head temps by about 50 degrees over the stock angled head

That is a good point about those bigger heads. I would need to run one of the square heads because of a forward-facing carburetor -- as the Puch head top fins would all have to be chopped off for it to work. I have a stock Fantic square head that I may try out at first.

use a BRN head, maybe create a small scoop near the base of the cylinder, it will be fine

Re: Fanless Minarelli V1 Polini Kit Set Up.

The fan totally helps. My polini kit runs about 100 degrees cooler with it than without.

But highest temps I saw without a fan was 450 after some hot laps on the track.

The BRN or the TEAM Garelli heads are also super legit

I run the TEAM head on my longest lasting, most blastiest bike

If you have the polini, you might as well run the fan + a Garelli head. If you’re fan-less, check dos or treats. Literally no downsides besides having to pul it to adjust timing

Re: Fanless Minarelli V1 Polini Kit Set Up.

Why would you not run a fan? I am a fan of the fan. I have a fanless V1 that I am going to put a Puch kit on.....but that is because it does have one.

It's for the three speed Minarelli (V3). No way to run a fan.

Thanks everyone. I'll try one of them slick BRN or Garelli heads. Will give a stock square head a whirl at first because it's all I've got laying around. Will check back with the progress.

they are the same head, just a bit more aggressive cut on the Garelli version

Re: Fanless Minarelli V1 Polini Kit Set Up.

I’m running a V1 Parma Kit on my FM470 3 speed with no fan. Haven’t taken it to a rally yet, but I’m confident after I road it in New Mexico for a long night ride.

Ohh also still rocking the oval head. Large rectangular head (spring 2020)

Let's do this.
